Good stuff- - - -EXCEPT- - - - -run, do not walk away from that Pertronix ignition! If you do a search on this site you'll find that there's about a 50/50 split of opinion about Pertronix. Would you choose to go to a doctor if half of his patients died suddenly? The Langdon's "Mini-HEI" uses GM original HEI parts which are available at any corner parts store, not proprietary electronics from who knows where, in a distributor housing modified to fit the stovebolt engine. I build the same type of system in my own shop, but most stovebolters don't have the machine tools necessary to make the housing fit. The large-diameter HEI from the electronic ignition 250 and 292 egines is a much closer fit, and it might be a little less spendy than the mini distributor.
